I need to know about some vines and how to start them. I collected the bittersweet seed in early winter, so they have already been stratified. The Japanese honeysuckle grows around our house here, and it too has berries. Do the seeds need stratification? And as far as the Virginia creeper ("Leaves of 5; let it survive"), does it grow from cuttings? If so, what time of the year do you cut? I have tried seed germination of Virginia creeper and the seeds didn't grow; I have only so far been able to transplant small plants. I wondered if cuttings will grow the plant, as some vines do.
